Until Recently, H

Until recently, H. erectus sites outside of Africa all have shown dates later than the earliest finds of species in Africa. This has led paleoanthropologists to assume that

A) the hominins who migrated to Asia and Europe descended from earlier Asian ancestors
B) the sites outside of Africa are misdated
C) the earliest finds in Africa are misdated
D) the hominins who migrated to Asia and Europe descended from earlier African ancestors
E) there is another, heretofore unknown hominin, who is the missing link
